The KB3100S is a rugged, industrial-grade circuit breaker designed to protect three-phase power systems. With a 100-amp rating and a 3-pole configuration, it delivers reliable fault interruption and dependable performance in demanding environments. This unit is ideal for maintenance, retrofit, and replacement projects where precise specs matter and compatibility is critical.
Designed for industrial use, the KB3100S emphasizes consistency and safety in power distribution. Its 3-pole design ensures balanced protection across all phases, which is essential for preventing phase imbalance and protecting motors and equipment on 3-phase systems. The 600V rating makes it suitable for a wide range of industrial applications, from manufacturing lines to heavy machinery controls, while the 100A capacity covers mid-size loads without overprotection. This balance helps minimize nuisance trips while providing strong protection when faults occur.
To ensure a perfect fit, verify that the replacement matches your panel’s specifications. The part number KB3100S is the most reliable reference for compatibility, so cross-check it against your current breaker or schematic. Before placing an order, confirm:
For a safe, effective installation, follow standard electrical safety practices and lockout/tagout procedures. Ensure the circuit is de-energized and test the line before replacement. After installation, perform a functional check to confirm proper trip operation and rated interrupting capacity. This approach helps protect downstream equipment, minimize downtime, and extend the lifespan of your power distribution system.
In short, the KB3100S delivers dependable protection for 3-phase systems up to 600V with a 100A rating, making it a precise, reliable choice for maintenance, retrofit, and replacement projects where spec alignment and compatibility are paramount.
